Lateral Mucosal Flap With Steroid-Eluting Implant in Revision Draf Type III Frontal Sinus Surgery

This technical note introduces a novel endoscopic strategy that integrates a laterally based endonasal mucosal flap with a bioabsorbable steroid-eluting implant to prevent restenosis following revision of Draf type III frontal sinus surgery. The vascularized flap is stabilized and maintained in close apposition to the underlying bone by a self-expanding bioabsorbable stent, which simultaneously provides sustained local corticosteroid delivery to reduce postoperative inflammation. By combining mechanical stabilization with targeted anti-inflammatory therapy, this technique represents a potentially innovative solution to promote mucosalization and maintain patency of the frontal neo-ostium in complex revision cases.
